Patent DE-2416623-A1 (DE)
Title: Road grip warning system for car - monitors relative speeds of driven and undriven wheels to measure wheel spin
Inventor: GUENTHER DETLEV
IPC: B60R16/023
Filed: 1974-04-05
Abstract: Both axles of the vehicle are fitted with wheel speed monitors whose outputs are coupled to a control circuit. This monitors the relative wheel speeds of the driven and undriven axles to determine the amount of wheel spin. If the wheel spin is more than a set value then warning systems are activated. A time delay relay keeps the warning operating for a set minimum time so that small patched of ice are catered for. The wheel speed indicators can be simple mechanical indicators of impulse generators coupled to electronic monitors.

Title: Powder cutter tip cooling system - has cooling air or carrier gas passed around ring channel
Inventor: HUEHNE ERWIN
IPC: B05B7/20
Filed: 1974-08-17
Abstract: The burner head is doubly fed, with powder-charged carrier gas (usually oxygen) in a central point-jet and with fuel gas in a concentric ring-jet. The compressed air used for cooling the burner is led away at the back of the burner head after passing round a ring-shaped channel near the front. Alternatively, the carrier gas for the powder medium is circulated around the channel and brought back afterwards to be charged with powder. In both designs a sheath is put round the central (powder-bearing) gas duct in the burner head, for the purpose of protecting the cooling system. The design avoids undesired cooling of the flame and also avoids interfering with the mixing of the combustion gases.

Title: Papain and -or ficin used in cereal decompsn process - gives faster mash iodine normality, higher final degree of fermentation and higher extract yields
Inventor: HARTMEIER WINFRIED DR
IPC: A23L7/104
Filed: 1974-10-12
Abstract: Disclosed is the 2-stage recovery of a cereal decompsn. prod. In the first stage 5-15% malt contg. >=80 SKB units per g was added to cereals and worked at 67-73 degrees C. In the second stage; amyloglucosidase or microbial and/or vegetable proteases was added and this stage (saccharification) carried out at 54-62 degrees C at a pref. pH of 5.5. The proteolytic enzyme action can largely (or totally) be carried out by adding papain and/or ficin to the mash initially. This modification leads to faster mash iodine normality, higher final degree of fermentation and higher extract yields. To achieve the same degree of decompsn. as in the Parent Patent, rather less protease needs to be added, thus effecting economies.

Title: Wear reducing device for brake linings - applies water to braking surfaces when brakes are only partially applied
Inventor: ERNST KARL AUGUST DR ING
IPC: F16D65/78
Filed: 1974-12-09
Abstract: There are four different cases where vehicle brakes have to be applied - (a) to hold the car stationary (b) to bring the care to rest (c) for an emergency stop and (d) for controlling speed in long descents in hilly country. It is only in the case (d) that serious wear occurs. If water is applied to the braking surface the efficiency of the brake is reduced. For controlling the speed of the vehicle when descending hills the full braking effect is not required so that water can be sprayed on the braking surfaces to reduce the lining wear. When needed for an emergency stop, the water is shut off and the lining dries very quickly.

Title: Master clock which stores timing signals during power failure - then emits at higher rate to catch up, only needs small standby battery
Inventor: MARTI RAYMOND
IPC: G04C13/02
Filed: 1975-01-08
Abstract: A master clock having an oscillator, a divider, a signal shaper, an output amplifier, and power feed either by means of an electric circuit or by means of a battery at the time of power failure in the circuit. A detector for circuit voltage is provided which upon a fall in circuit voltage switches signals from the output of the divider to an electronic memory. Upon reestablishment of power in the circuit, the time signals are fed out of the memory at an accelerated rate to cause the secondary clock controlled by the master clock to catch up. It is thus possible to use only a small and inexpensive standby battery for use during power failure.

Patent DE-2522505-A1 (DE)
IPC: C02F11/123
Filed: 1975-05-21
Abstract: For the dewatering of sludge (16), the latter is spread out on an endless perforated belt (18). The sludge subsequently passes through four consecutive dewatering zones, specifically a filter zone (10), a suction zone (12), a compression zone (14) and a milling zone (15). The milling zone (15) has, in order to exert a shear stress on the compacted sludge, rollers (18) which are arranged in succession, horizontally in the direction of transport and vertically displaced with respect to one another and which have axes which are horizontal and are at right angles to the direction of transport. This results in better dewatering of the sludge solids and less contamination of the perforated belt by comparison with the process and the apparatus for dewatering sludge in three consecutive process steps. <IMAGE>

Title: Pathogenic fungi control using blood or haemoglobin - which are environmentally acceptable, nontoxic and avoid undesirable side effects of synthetic fungicides
Inventor: DOCKNER TONI DR
IPC: A01N63/50
Filed: 1975-05-24
Abstract: A pathogenic fungi are controlled using blood or haemoglobin as the fungicide. Blood esp. animal blood (e.g. ox blood) has fungicidal activity as has the haemoglobin obtd. from it. Both substs. also exhibit bactericidal activity. These natural prods. are environmentally acceptable and non-toxic. They avoid the undesirable side effects of many synthetic fungicides e.g. mutagenicity, tetatogenicity, carcinogenicity. Haemoglobin acts against pathogenic plant fungi e.g. Rizoctonia solani and Pernospora. Ox blood inhibits the growth of moulds on glucose agar as does haemoglobin.

IPC: G01R19/14
Filed: 1975-05-30
Abstract: A voltage monitoring circuit using optical indication of the presence of voltage is designed to operate with both alternating and direct voltages and to maintain constant indication brightness over a large voltage range. The circuit is simply and cheaply constructed. Two antiparallel luminescence diodes (1, 2) are connected in series with a current stabilising impedance (3) whose resistance varies with temp. until a constant level of resistance is reached. A resistor (4) in parallel with the impedance (3) enhances the current stabilising effect. Both diodes are illuminated when an alternating voltage is applied, and when a direct voltage is applied the forward conducting diode is illuminated.
